ath9k: fix using sta->drv_priv before initializing it
A station pointer can be passed to the driver on tx, before it has been
marked as associated. Since ath9k_sta_state was initializing the entry
too late, it resulted in some spurious crashes.
Fixes: df3c6eb34da5 ("ath9k: Use sta_state() callback")
